Varicella (Chickenpox) Vaccine FAQs

Most commonly known as chickenpox, varicella is a highly contagious viral disease. Until 1995, when the varicella vaccine was implemented in the US, chickenpox was a common illness among kids under 12 years old. The first symptoms include fever, headache, sore throat, or stomachache, followed by a red, itchy skin rash that turns into blisters. It can affect all parts of the body.

Since 1995, the varicella vaccine has become one of the many routine immunizations children receive in the first years of life.

Children receive two doses of the varicella vaccine. The first dose is given at 12 to 15 months of age. The second dose is given before the start of kindergarten at 4 to 6 years of age.

The varicella vaccine significantly reduces the chances of getting chickenpox. If a vaccinated child does get chickenpox, it tends to be much milder and last for a shorter period of time than in those who are not immunized.

Adolescents and adults 13 years of age and older who have never had chickenpox or been immunized against it should get two doses, at least 28 days apart. Because chickenpox is highly contagious, the varicella vaccine is especially important if you are a:
